"自然显示，随着智力的增长，痛苦的能力也会增加。"

Simplified Meaning:

As living things become smarter, they can feel more pain. Think about a child and an adult. A child might cry if they scrape their knee, but forget about it soon after. An adult, on the other hand, can feel emotional pain from losing a job, worrying about the future, or remembering past mistakes. This happens because adults think about more complex things and understand more about life. By becoming more aware, humans can enjoy things in a deeper way, but also suffer more when things go wrong. For instance, someone who loves animals might feel deep sadness when they see an injured animal. While intelligence helps us solve problems and create wonderful things, it also makes us feel both physical and emotional pain more intensely. To manage this, we can use our intelligence to find ways to cope with pain, like talking to friends or doing activities we enjoy. So, while being smart has its challenges, we can use that same intelligence to make our lives better and support others too.
